Question

Two capacitor 3.0 pico Farad and 6.0 pico Farad are connected in series. If the capacitor connected to a potential difference of 1000v, calculate
a. Magnitude of the charge on each capacitor
b. The potential difference across the capacitor

Answer 1

c = q/v
same q on each, call it q
so
c1 V1 = c2 V2 so V2 = (c1/c2) V1
and
V1 + V2 = 1000

V1 + (c1/c2)V1 = 1000
but c1/c2 = 3/6 = .5
so
1.5 V1 = 1000
V1 = 667
V2 = 333
I think you can go back and get q = v c for each
